]FontSavingArgs.KeepFontStreamOpen property
Specifies whether Aspose.Words should keep the stream open or close it after saving a font.

and Aspose.Words will close the stream you provided in the FontStream
property after writing a font into it. Specify true
to keep the stream open.
Examples
Shows how to define custom logic for exporting fonts when saving to HTML.
public void SaveExportedFonts()
{
Document doc = new Document(MyDir + "Rendering.docx");
// Configure a SaveOptions object to export fonts to separate files.
// Set a callback that will handle font saving in a custom manner.
HtmlSaveOptions options = new HtmlSaveOptions
{
ExportFontResources = true,
FontSavingCallback = new HandleFontSaving()
};
// The callback will export .ttf files and save them alongside the output document.
doc.Save(ArtifactsDir + "HtmlSaveOptions.SaveExportedFonts.html", options);
foreach (string fontFilename in Array.FindAll(Directory.GetFiles(ArtifactsDir), s => s.EndsWith(".ttf")))
{
Console.WriteLine(fontFilename);
}
}
/// <summary>
/// Prints information about exported fonts and saves them in the same local system folder as their output .html.
/// </summary>
public class HandleFontSaving : IFontSavingCallback
{
void IFontSavingCallback.FontSaving(FontSavingArgs args)
{
Console.Write($"Font:\t{args.FontFamilyName}");
if (args.Bold) Console.Write(", bold");
if (args.Italic) Console.Write(", italic");
Console.WriteLine($"\nSource:\t{args.OriginalFileName}, {args.OriginalFileSize} bytes\n");
// We can also access the source document from here.
Assert.True(args.Document.OriginalFileName.EndsWith("Rendering.docx"));
Assert.True(args.IsExportNeeded);
Assert.True(args.IsSubsettingNeeded);
// There are two ways of saving an exported font.
// 1 - Save it to a local file system location:
args.FontFileName = args.OriginalFileName.Split(Path.DirectorySeparatorChar).Last();
// 2 - Save it to a stream:
args.FontStream =
new FileStream(ArtifactsDir + args.OriginalFileName.Split(Path.DirectorySeparatorChar).Last(), FileMode.Create);
Assert.False(args.KeepFontStreamOpen);
}
